However, the diagnostically low iodine data from mid-Proterozoic shallow-water carbonates, relative to those of the bracketing time intervals, are consistent with a dynamic chemocline and anoxic waters that would have episodically mixed upward and laterally into the shallow oceans.
In this context, the proteins' motions will all occur more slowly and as such can be represented by Boltzmann distributions that bracket the time range from milliseconds (the observed time scale for enzyme function) to femtoseconds (the minimal time scale for the tunneling event).
"You can find similar people, whether they're in the same income bracket or time schedule or a healthy person," Ms. Brown said.
It is the most important financial moment of the year for many people in the bottom half of the wage bracket, a time to pay off old bills, make car repairs, buy children clothes and maybe make a big purchase like a refrigerator or a TV.

In these sort of studies, it is best that the leaves all be frozen within a small bracket of time, all in the same day, with the same light and temperature.
The primary goal of the analysis was to bracket the time of divergence of the horse breed mtDNA sequences; a completely thorough molecular dating exercise was not attempted here, as this would take a separate complex study at least involving the incorporation of many partial mtDNA sequences available from subfossil equines [ 60].
Most offices have an "emergency" bracket of time when urgent patients can be scheduled.
